CHOICE A:
Size: 18x7.5
Bolt Pattern: 5x100 or 5x114.3
Offset: +48mm
CHOICE B:
Size: 18x7.5
Bolt Pattern: 5x100 or 5x114.3
Offset: +42mm
Will these rims fit an ALL STOCK 2007 MAZDASPEED 6?
I'm not really a fan of either style wheel, but its your car and its your decision that matters.
As for fitment, the 48mm offset is going to work a lot better for you without rolling the fenders.
And you want 114.3x5 bolt pattern, FYI. Center hub bore needs to be 67.1mm or larger. If larger you can use hub-centric rings.
